The correlation of the spinoglenoid ganglion cyst size with the electrophysiological alterations of suprascapular nerve and the rotator cuff muscle power.

BACKGROUND: Although various treatment options are available for spinoglenoid cyst, including conservative and surgical methods, there is no standard guideline for its surgical decompression. Thus, the purpose of the study was to correlate the size of the spinoglenoid notch ganglion cyst (GC) as revealed by magnetic resonance imaging (MRI) with electrophysiological alterations, muscle power, and pain severity, and to estimate a cut-off value of cyst size to perform a decompression. METHODS: Between January 2010 and January 2018, the patients with a GC at the spinoglenoid notch diagnosed on MRI, and who had a minimum follow-up of 2 years after the decompression were included. Maximum cyst diameter as measured on MRI was used for comparison. Electromyography (EMG) and nerve conduction velocity (NCV) studies were performed before the surgery. Peak torque deficit (PTD) percentage compared to opposite shoulder was calculated preoperatively and at 1 year after surgery. Pain severity was estimated using visual analogue scale (VAS) preoperatively. RESULTS: Ten (50%) of 20 patients with GC > 2.2 cm and 1 (5.9%) of 17 patients with GC < 2.2 cm showed EMG/NCV abnormalities (p = 0.019). There was a correlation between the cyst size and the positive EMG/NCV findings (Correlation coefficient (CC) = 0.535, p < 0.001). The preoperative peak torque deficit on the external rotation was correlated with the positive EMG/NCV findings (CC = 0.373, p = 0.021). The PTD was improved significantly at 1 year postoperatively in patients with a GC size >2.2 cm (p = 0.029). The cyst size was not related to the preoperative pain VAS and muscle power. CONCLUSIONS: The spinoglenoid cyst size >2.2 cm, but not pain severity or muscle power, correlates with the positive finding of EMG for compressive suprascapular neuropathy. The GC size >2.2 cm can be a reference to decide the need of decompression surgery. LEVEL OF EVIDENCE: IV, case series.

A retrospective cohort study examining secondary prevention post stroke in primary care in an Asian setting.

BACKGROUND: Stroke is one of the top contributors to burden of disability-adjusted life-years worldwide. Family physicians have key role in optimising secondary prevention following stroke by managing clinical risk factors and promoting overall control in accordance with clinical practice guidelines. METHODS: Our objectives were: (i) to examine level of overall risk factor control together with control of singular risk factors one-year after an index-stroke event in individuals attending primary care facility and (ii) to describe factors associated with satisfactory risk factors control in individuals following stroke. STUDY DESIGN: Retrospective cohort study. We conducted a study looking retrospectively at records from our electronic chronic disease database. Our study included individuals following stroke who visited primary care setting in Singapore between January 2012 to December 2016. RESULTS: There were 24,240 individuals in our study. Overall control was better in individuals without diabetes following stroke (49.2%) as compared to those with diabetes (28.1%). Among individuals without diabetes following stroke, factors significantly associated with overall control were sex (male) [OR (reference: female): 1.23, 95% CI: 1.10, 1.39], ethnicity (Malay) [OR (reference: Chinese): 0.72, 95% CI: 0.58, 0.90], BMI (high risk) [OR (reference: low risk): 0.72, 95% CI: 0.62, 0.84) and atrial fibrillation [OR: 1.47, 95% CI: 1.21, 1.78]. Among individuals with diabetes following stroke, factors significantly associated with overall control were sex (male) [OR (reference: female): 1.28, 95% CI: 1.12, 1.46], ethnicity (Malay) [OR (reference: Chinese): 0.81, 95% CI: 0.65, 0.99], ethnicity (Indian) [OR (reference: Chinese): 0.70, 95% CI: 0.55, 0.88], BMI (high risk) [OR (reference: low risk): 0.71, 95% CI: 0.59, 0.84), BMI (moderate risk) [OR (reference: low risk): 0.84, 95% CI: 0.72, 0.98), atrial fibrillation [OR: 1.24; 95% CI: 1.02, 1.51], chronic kidney disease [OR: 0.63, 95% CI: 0.54, 0.72] and smoking status [OR: 0.68, 95% CI: 0.54, 0.88]. CONCLUSION: We reported sub-optimal level of overall control. Among individuals following stroke, those with diabetes had higher proportion of sub-optimal control as compared to those without diabetes. Irrespective of diabetic status, being female, having high BMI, and of Malay ethnicity as compared to Chinese ethnicity were associated with poorer overall risk factor control.

New mobile-bearing TKA with unique ball and socket post-cam mechanism offers similar function and stability with better prosthesis fit and gap balancing compared to an established fixed-bearing prosthesis.

PURPOSE: A mobile-bearing (MB) posterior-stabilized total knee arthroplasty (TKA) system with ball and socket post-cam mechanism has been developed with the aims of better prosthesis fit and enhanced stability. However, the data are limited to compare its clinical outcomes with an already established fixed-bearing (FB) implant design. METHODS: This is a prospective randomized study comparing 260 patients in the MB group and 133 patients in FB group with a minimum 2 years of follow-up. Intraoperative variables, post-operative functional outcomes and incidence of adverse events were compared. RESULTS: MB group showed better prosthesis fit as the incidence of over-hang of femoral component at junction (medial: 1% vs. 5% and lateral: 2% vs 4%, p < 0.001) and trochlea (medial: 2% vs 30%, p = 0.042 and lateral: 13% vs 21%, p = 0.015) was less than FB group. MB group also showed better gap balancing as the incidence of medio-lateral gap difference more than 2 mm was less in flexion (2.3% vs. 16%, p < 0.001) and extension (3.1% vs. 9.8%, p = 0.005). Post-operative functional outcomes and incidence of adverse events showed no difference between the two groups at 2 years. CONCLUSIONS: New MB design offers similar functional outcomes and stability along with better intraoperative prosthesis fit and gap balancing compared to an established fixed-bearing design. Hence, this new MB design could be an alternative prosthesis of choice for posterior-stabilized TKA. LEVEL OF EVIDENCE: I.

Low iodine diet in differentiated thyroid cancer: a review.

Radioactive iodine (RAI) ablation is a beneficial, adjuvant therapy for the management of differentiated thyroid cancer (DTC) after thyroidectomy. The goal of RAI is to destroy remnant thyroid and microscopic cancerous tissue. Radioactive iodine uptake is enhanced by elevating TSH levels and initiating a low iodine diet (LID) prior to ablation. An ideal LID should preferably not exceed 50 mcg/day of dietary iodine for 1-2 weeks, although the duration may be shortened to a week with a structured patient education programme. A pre-ablation spot urinary iodine concentration (UIC) of <100 mcg/l and/or a urinary iodine to creatinine ratio (UICR) of <100 mcg/gCr would support an adequate LID preparation. Hyponatraemia, most likely due to iatrogenic hypothyroidism, is a potential side effect associated with LID and occurs during and a few days after the LID. Although the overall incidence of hyponatraemia is low, patients at high risk (older age, female sex, use of thiazide diuretics) may benefit from serum sodium monitoring. The existing evidence on the impact of LID on RAI ablation has been largely inconsistent due to retrospective study designs and the lack of an objective measurement of urinary iodine levels. Future large prospective randomized control trials are needed to elucidate and confirm the crucial role of LID in achieving successful RAI ablation and greater disease-free survival in DTC.

Cancer Cell Targeting Using Folic Acid/Anti-HER2 Antibody Conjugated Fluorescent CdSe/CdS/ZnS-Mercaptopropionic Acid and CdTe-Mercaptosuccinic Acid Quantum Dots.

CdSe/CdS/ZnS and CdTe quantum dots (QDs) were synthesized by successive ion layer adsorption and reaction (SILAR) technique and direct aqueous synthesis respectively using thiol stabilizers. Synthesized CdSe/CdS/ZnS and CdTe QDs stabilized with 3-mercaptopropionic acid (MPA) and mercaptosuccinic acid (MSA) were used as fluorescent labels after conjugation with folic acid (FA) and anti-HER2 antibodies. Photoluminescence quantum yield of folated CdSe/CdS/ZnS-MPA and CdTe-MSA QDs was 59% and 77% than that of non-folated hydrophilic QDs. The folate receptor-mediated delivery of folic acid-conjugated CdTe-MSA and CdSe/CdS/ZnS-MPA QDs showed higher cellular internalization as observed by confocal laser scanning microscopic studies. Folated and non-folated CdTe-MSA QDs were highly toxic and exhibited only 10% cell viability as compared to > 80% cell viability with CdSe/CdS/ZnS-MPA QDs over the concentration ranging from 3.38 to 50 pmoles. Immunohistochemistry (IHC) results of human breast cancer tissue samples showed positive results with anti-HER2 antibody conjugated CdSe/CdS/ZnS-MPA QDs with better sensitivity and specificity as compared to conventional IHC analysis using diaminobenzedene staining.

Pitfalls in the diagnosis and management of Cushing's syndrome.

Despite many recent advances, the management of patients with Cushing's disease continues to be challenging. Cushing's syndrome is a complex metabolic disorder that is a result of excess glucocorticoids. Excluding the exogenous causes, adrenocorticotropic hormone-secreting pituitary adenomas account for nearly 70% of all cases of Cushing's syndrome. The suspicion, diagnosis, and differential diagnosis require a logical systematic approach with attention paid to key details at each investigational step. A diagnosis of endogenous Cushing's syndrome is usually suspected in patients with clinical symptoms and confirmed by using multiple biochemical tests. Each of the biochemical tests used to establish the diagnosis has limitations that need to be considered for proper interpretation. Although some tests determine the total daily urinary excretion of cortisol, many others rely on measurements of serum cortisol at baseline and after stimulation (e.g., after corticotropin-releasing hormone) or suppression (e.g., dexamethasone) with agents that influence the hypothalamic-pituitary-adrenal axis. Other tests (e.g., measurements of late-night salivary cortisol concentration) rely on alterations in the diurnal rhythm of cortisol secretion. Because more than 90% of the cortisol in the circulation is protein bound, any alteration in the binding proteins (transcortin and albumin) will automatically influence the measured level and confound the interpretation of stimulation and suppression data, which are the basis for establishing the diagnosis of Cushing's syndrome. Although measuring late-night salivary cortisol seems to be an excellent initial test for hypercortisolism, it may be confounded by poor sampling methods and contamination. Measurements of 24-hour urinary free-cortisol excretion could be misleading in the presence of some pathological and physiological conditions. Dexamethasone suppression tests can be affected by illnesses that alter the absorption of the drug (e.g., malabsorption, celiac disease) and by the concurrent use of medications that interfere with its metabolism (e.g., inducers and inhibitors of the P450 enzyme system). In this review, the authors aim to review the pitfalls commonly encountered in the workup of patients suspected to have hypercortisolism. The optimal diagnosis and therapy for patients with Cushing's disease require the thorough and close coordination and involvement of all members of the management team.

MIPModDB: a central resource for the superfamily of major intrinsic proteins.

The channel proteins belonging to the major intrinsic proteins (MIP) superfamily are diverse and are found in all forms of life. Water-transporting aquaporin and glycerol-specific aquaglyceroporin are the prototype members of the MIP superfamily. MIPs have also been shown to transport other neutral molecules and gases across the membrane. They have internal homology and possess conserved sequence motifs. By analyzing a large number of publicly available genome sequences, we have identified more than 1000 MIPs from diverse organisms. We have developed a database MIPModDB which will be a unified resource for all MIPs. For each MIP entry, this database contains information about the source, gene structure, sequence features, substitutions in the conserved NPA motifs, structural model, the residues forming the selectivity filter and channel radius profile. For selected set of MIPs, it is possible to derive structure-based sequence alignment and evolutionary relationship. Sequences and structures of selected MIPs can be downloaded from MIPModDB database which is freely available at http://bioinfo.iitk.ac.in/MIPModDB.

Three-dimensional conformal brachytherapy boost in locally recurrent or residual cervical carcinoma: does it impact clinical outcome?

AIM: To analyze the influence of computed tomography (CT)-guided 3D conformal interstitial brachytherapy (3D-IBT) boost for better coverage of target volumes and study the diametric impact to organ at risk in patients with post-surgery recurrent and residual cervical cancer. MATERIAL AND METHODS: Fourteen consecutive patients with recurrent or residual cervical cancer who were treated with interstitial brachytherapy as a boost were included in the study. All patients received 50.4 Gy external radiation (EBRT) to whole pelvis with conformal technique to reduce the dose to bowel. The clinical target volume (CTV) and organs at risk were contoured on CT scan with gold seeds being a surrogate marker of initial tumor extent implanted before commencing treatment. The median dose of prescription was 10.5-12Gy in 3 fractions. Dose volume histogram was calculated to evaluate the dose that covers 100% and 90% of the target volume and dose to the bladder, rectum and bowel (2 mL, 1 mL volume). RESULTS: The median follow-up was 12 months (range 6-18). The doses to CTV (D90, D100) ranged from 1141 to 2014 cGy, and 585 to 969 cGy, respectively. The mean cumulative 2-mL rectal, bladder and bowel doses were 66.70, 73.15 and 61.01Gy, respectively. Rectal toxicity of grade 2 or more had a strong correlation with the dose delivered (Spearman's correlation, 0.950). The local control rate at one year was 92% with failure seen in one patient only. CONCLUSION: Conformal EBRT supplemented with 3D-IBT seems to be a practical and appropriate approach to give the most optimal therapeutic benefit with the least side-effects in postoperative recurrent and residual cervical cancer patients.

Impairment of immune systems in diabetes.

Type 1 diabetes mellitus (T1DM) is an autoimmune disease that involves the progressive destruction of the insulin-producing beta cells in the islets of langerhans. It is a complex process that results from the loss of tolerance to insulin and other beta-cell-specific antigens. Various genetic and environmental factors have been studied so far, but precise causation has yet to be established. Numerous studies in rodents and human subjects have been performed in order to elucidate the role of B and T cells, which determine the risk of development and progression of diabetes. These studies have demonstrated that while T1DM is fundamentally a T-cell-mediated autoimmune response, the development of this disease results from complex interactions between the adaptive and innate immune systems, with numerous cell types thought to contribute to pathogenesis. Like any complex disease, the variation in severity and incidence of T1DM can be attributed to a combination of genetic and environmental factors.

Disengagement of tibial insert locking pin in total knee arthroplasty - A rare failure case report.

Total Knee Arthroplasty (TKA) has seen many advancements over the years. One such advancement is development of locking mechanism for polyethylene insert in modular implants. It aims to reduce micro motion and wear problems. Disengagement of locking pin from insert after primary TKA without trauma is rare complication. The author describes a rare case of disengagement of the polyethylene insert locking pin in primary total knee arthroplasty. Disengagement of the locking clip was observed 8 months after index operation without any trauma.

Primary ectopic breast carcinoma arising in the inguinal region in a male patient.

Carcinoma arising in ectopic breast tissue is a rare entity, especially in males, in whom the diagnosis is often delayed due to a low index of suspicion. Conventional imaging techniques fail to characterize the tumor, adding further to the diagnostic dilemma. We report the first case in our knowledge of an extramammary primary breast carcinoma arising in the inguinal region in a male. Our patient, a 69-year-old male, presented with a swelling in the left inguinal region, which was excised and diagnosed as luminal A type invasive ductal carcinoma. He received adjuvant external beam radiotherapy (50 Gy administered in 25 fractions) and tamoxifen. A follow-up examination performed 6 months after the completion of the last dose of radiotherapy showed no residual disease. The modalities of treatment for such tumors have been discussed, with emphasis on surgery and radiotherapy, given the aggressive nature of the disease.

Obesity does not increase complications following pancreatic surgery.

BACKGROUND: Recent evidence suggests that the quantity of intra-abdominal fat may be a more important predictor of postoperative complications than body mass index (BMI). We hypothesized that increased intra-abdominal fat would be associated with longer operations, increased blood loss, more complications, and prolonged length of stay after pancreatic resection. METHODS: Retrospective cohort study. Intra-abdominal fat was quantified using CT imaging, and patients were divided into three groups (low, moderate, high). Unconditional multiple logistic regression was used to evaluate the relationship between obesity measures and complications. RESULTS: Between 2002 and 2010, 255 patients underwent pancreaticoduodenectomy or distal pancreatectomy, and 201 had preoperative CT imaging available for review. Operative time was significantly prolonged in patients with high quantities of intra-abdominal fat compared with those with low fat quantity (median 438 versus 354 min, P < 0.05), while BMI was not associated with changes in duration of surgery. Neither obesity defined by BMI (OR 0.90, 95% CI 0.36-2.21) nor visceral fat (OR 1.20, 95% CI 0.46-3.16) significantly predicted risk of complications. Median length of stay was similar in patients who were obese by BMI (7 versus 7.5 d) or amount of intra-abdominal fat (7 d). CONCLUSIONS: Intra-abdominal fat was a better predictor than BMI for determining length of procedure. However, in contrast to previous studies evaluating abdominal surgery, neither BMI nor intra-abdominal fat significantly predicted risk of complication or length of hospital stay. Further research is needed to determine the best measure to assist in risk prediction of obese patients undergoing pancreatic surgery.

Extramedullary plasmacytoma presenting as a mediastinal mass.

Extramedullary plasmacytoma (EMP) is a plasma cell neoplasm without bone marrow involvement or other systemic characteristics of multiple myeloma. Few large-scale clinical studies have been conducted because of the rarity of EMP, especially when it arises from the mediastinum. Herein we report a rare case of solitary mediastinal plasmacytoma with reactive pleural effusion. A 58-year-old female presented with grade 4 dyspnea and dysphagia, with a mediastinal mass observed with on PET. CT-guided biopsy results were suggestive of IgG kappa-type EMP arising from the anterior mediastinum. The patient was treated with local radiotherapy to the mediastinum, and had clinical and radiological response s were good. Radiotherapy is an effective treatment for mediastinal EMP, but a complete workup is mandatory, including PET, as the majority of such masses coexist with multiple myeloma.

New Horizons for Diagnostic Pitfalls of Cerebral Venous Thrombosis: Clinical Utility of a Newly Developed Cerebral Venous Thrombosis Diagnostic Score: A Case Report and Literature Review.

BACKGROUND Diagnosing cerebral venous thrombosis (CVT) poses significant challenges owing to a nonspecific clinical presentation, poorly correlated laboratory biomarkers, and low sensitivity of non-contrast head computed tomography (CT). We describe a case of missed CVT diagnosis, due to low clinical suspicion and nonrecognition of anemia as a prothrombotic factor, especially during an ulcerative colitis (UC) flare. A recently proposed CVT clinical probability score can guide clinicians in pursuing further neurovascular imaging. CASE REPORT A 35-year-old man, with treatment-naive UC, presented to the Emergency Department (ED) with new-onset diffuse headache, 4 weeks of bloody diarrhea, and weight loss. Initial ED laboratory studies revealed severe anemia and unremarkable non-contrast head CT. Two days later, the patient returned to the ED for worsening headache. Non-contrast head CT revealed a left temporal hypodensity. This was later confirmed as acute ischemia on magnetic resonance imaging (MRI). MR venogram revealed thrombosis of the left transverse and sigmoid sinuses, leading to initiation of therapeutic subcutaneous anticoagulation. Repeat MRI, secondary to worsening headache, revealed the development of petechial hemorrhages within the core of venous ischemia in the left temporal lobe. Therapeutic anticoagulation, along with symptomatic management of UC, led to clinical stabilization. CONCLUSIONS CVT should be suspected in patients with UC, especially in the context of anemia, presenting with new-onset or worsening headaches. Recognizing anemia as a thrombogenic factor is crucial. Diagnosis of CVT is challenging due to non-focal symptoms and poorly correlating diagnostic tests. We endorse implementing the CVT clinical probability score into AHA/ASA CVT guidelines to enhance diagnostic accuracy.

Isolated Pulvinar/Hockey Stick Sign in Nonalcoholic Wernicke's Encephalopathy.

BACKGROUND Wernicke's encephalopathy (WE), a commonly misdiagnosed and underdiagnosed pathology, presents with altered mental status, ataxia, and ophthalmoplegia. WE is most commonly caused by excessive alcohol use, but also has diverse nonalcoholic etiologies. Here we describe 2 cases of nonalcoholic WE with different etiologies that were initially misdiagnosed due to lack of correlation of magnetic resonance imaging (MRI) findings with clinical information. CASE REPORT Patient A, a 50-year-old woman with recent gastric sleeve surgery, presented with horizontal gaze-evoked nystagmus, ataxia, and altered mental status. MRI fluid-attenuated inversion recovery (FLAIR) revealed isolated bilateral, symmetrical, thalamic hyperintensities, initially diagnosed as variant Creutzfeldt-Jakob disease. A review of imaging and clinical presentation provided an alternate diagnosis of nonalcoholic WE secondary to nutritional deficiency. Intravenous (IV) thiamine improved symptoms with resolution of MRI findings 6 months later. Patient B, a 64-year-old woman, presented with nausea, vomiting, dizziness, altered mental status, and weight loss. MRI FLAIR revealed isolated bilateral, symmetrical, thalamic hyperintensities, initially determined to be ischemia, prompting stroke management. A diagnosis of nonalcoholic WE was suggested, given the patient's low thiamine levels and history of malnutrition, and was confirmed by her excellent therapeutic response to IV thiamine. CONCLUSIONS Nonalcoholic WE remains a challenging diagnosis because of the variable clinical presentation, myriad of underlying etiologies, and lack of standardized diagnostic laboratory tests. A multidisciplinary approach with close collaboration between the radiologist and clinical care team is critical to narrow down the differential and initiate correct management. WE is a reversible disease with catastrophic consequences if it is not recognized and treated promptly.

Standardization and validation of Vero cell assay for potency estimation of diphtheria antitoxin serum.

Diphtheria toxin has the capacity to block protein synthesis in cultured mammalian cells, and thus causing cell death. This capacity of diphtheria toxin was utilized for in-vitro neutralization test to determine antibody titer, using Vero cells, which have been found to be susceptible to diphtheria toxin. In the present study, a Vero cell assay was standardized and validated for potency estimation of diphtheria antitoxin serum (DATS). The results obtained by Vero cell assay were compared with in-vivo biological assay. High degree of correlation (+0.98) was found between in-vivo biological assay and in-vitro Vero cell assay. The assay has also been found to be effective in determining the rising antibody titer in the equines inducted in DATS production. The present study indicated that although biological assays hold the key for final potency estimations till date but in the future scenario in-vitro Vero cell assay may be a good alternative to in-vivo biological assay.

Radiological evaluation of pelvic inlet and outlet radiographic view in Indian population.

BACKGROUND: Pelvic fractures represent one of the most challenging clinical problems in which an urgent multidisciplinary approach is required. The early management in a suspected pelvic fracture starts with the good radiological evaluation. The standard radiographic view includes the anteroposterior, inlet and outlet views. The inlet and outlet views are taken with 45° tilt from anteroposterior plane. However, recent studies have shown that there is significant individual variation within the population and these values should be redefined. MATERIAL AND METHODS: This is a retrospective study carried out in a tertiary care teaching institute. Total 110 patients (including 42 female and 68 male patients) of age older than 18 years, who had a routine pelvic Computed Tomography (CT) scan performed for any indications unrelated to pelvic pathologies were included. STATISTICAL ANALYSIS: Mean and standard deviation were calculated. For each angle measured, the effect of age was determined and a comparison was made between male and female patients, p value <0.05 is considered significant. RESULTS: The mean angle of caudal tilt for the ideal screening inlet view was 33° +/-8 (16.3-31.3) and the mean angle of cephalic tilt for the ideal screening outlet view was 56° +/-9 (51.6-81.8). CONCLUSION: This study re-evaluated the optimal inlet and outlet angles in Indians and demonstrated that the mean angles needed to create an ideal pelvic inlet and outlet views are 33° and 56° respectively.

Inpatient diabetes management by specialized diabetes team versus primary service team in non-critical care units: impact on 30-day readmission rate and hospital cost.

OBJECTIVE: We compared the cost-effectiveness of two inpatient diabetes care models: one offered by a specialized diabetes team (SDT) versus a primary service team (PST). RESEARCH DESIGN AND METHODS: We retrospectively evaluated 756 hospital admissions of patients with diabetes to non-critical care units over 6 months. Out of 392 patients who met the eligibility criteria, 262 were matched 1:1 based on the mean of the initial four blood glucose (BG) values after admission. Primary outcomes were 30-day readmission rate and frequency, hospital length of stay (LOS) and estimated hospital cost. Secondary outcomes included glycemic control and BG variability. RESULTS: Diabetes complexity and in-hospital complications were significantly higher among patients treated by SDT versus PST. Thirty-day readmission rate to medical services was lower by 30.5% in the SDT group versus the PST group (P<0.001), while 30-day readmission rate to surgical services was 5% higher in the SDT group versus the PST group (P<0.05), but frequency of 30-day readmissions was lower (1.1 vs 1.6 times, P<0.05). LOS in medical services was not different between the two groups, but it was significantly longer in surgical services in SDT (P<0.05). However, LOS was significantly lower in patients who were seen by SDT during the first 24 hours of admission compared with those who were seen after that (4.7 vs 6.1 days, P<0.001). Compliance to follow-up was higher in the SDT group. These changes were translated into considerable cost saving. CONCLUSIONS: Inpatient diabetes management by an SDT significantly reduces 30-day readmission rate to medical services, reduces inpatient diabetes cost, and improves transition of care and adherence to follow-up. SDT consultation during the first 24 hours of admission was associated with a significantly shorter hospital LOS.
